AIPPARATUS FOR AERATING LIQUIDS.

Application filed. December 21, 1925, Serial No. 76,880, and in GreatBritain December 20, 1924.

This invention relates to apparatus for aerating liquids and is moreparticularly intended for use in making soda water, the apparatus beingof the kind that is supported in its working position by the deliverypipe of the aerating gas container or cylinderto which it is adapted tobe attached and in which a bottle guard or shield is provided to coverthe bottle containing the liquid to be aerated so as to prevent injuryto the operator in the event of the bottle bursting during the aeratingoperation.

According to this invention the apparatus is provided with means wherebythe movement which efiiects the engagement of the bottle containing theliquid to be aerated with the aerating gas inlet orifice of theapparatus also causes the bottle guard or'shield to assume theprotecting or closed position around the bottle the movement of thebottle guard or shield into this position being timed to take placepreferably before the bottle is fully engaged with the said aerating gasinlet orifice and the disengagement of the bottle therefrom being timedto take place guard or shield 1, but shewing the bottle guard or shield:in the protecting or closed position.

Figure l is a plan view shewing the bottle guard or shield in the openposition in full lines, in the partially closed position in dot and dashlines and in the fully closed position in dotted lines.

Figures 5, 6 and 7 are similar views to Figures 1, 2 and 3 of amodification.

Figure 8 is a plan view showing the bottle guard or shield in the openposition in full lines and in the protecting or closed position in dotand dash lines, and

Fig. 9 is an enlarged sectional view taken a on line 99 of Fig. 4:showing the hinged connection between the stationary part and themovable part of the bottle guard.

Like letters of reference are used throughout the drawings to denotesimilar parts.

The apparatus comprises a frame consisting of two upright portions A, Aand a horizontal portion A the frame being conveniently made by bendinga bar or strip of metal to .the shape shewn. The frame is attached atits upper end to a cross piece B by means of screws C, C, C, C, thismode of attachment enabling frames of varying lengths to he used to suitdifferent sizes of bottles. The horizontal portion A of the framecarries a platform or support D on which the bottle containing theliquid to be aerated stands. In Figures 1 to 4 the said platform isadjustably mounted in the portion A by means of the screw threaded stemcl so that by rotating the handle at thereon the platform can be raisedor lowered in the frame. The bottle guard or shield consists of astationary part E and a movable part E both of semi-circular shape. InFigures 1 to 4 theiixed part E is attached to a disc F having ascrew-threaded portion F which engages with a correspondinglyscrew-threaded portion in the cross piece B through which it extends andthe movable part E is hinged vertically to the fixed part E. 'The saiddisc F and the screw-threaded portion F have a passage 7? through themwhich passage communicates with a lateral pipe G provided with a jointby which it can be connected to the outlet pipe of the aerating gascontainer or cylinder, said pipe serving to support the apparatus in itsworking position on the aerating gas container orv cylinder and toconduct the aerating gas therefrom. The passage terminates at its innerend in a conically shaped nozzle H which constitutes the aerating gasinlet orifice of the apparatus and against which the bottlejcontainingthe liquid to be aerated is engaged during the aerating operation. Theframe is provided with a handle J by which it can be turned on theaforesaid screwthreaded portion F. In use the frame is turned orangularly displaced by means of the said handle on the screw-threadedporliquid to be aerated is then stood on the platform D. The frame isthen turned inthe opposite direction which causes it to rise on thescrew-tl'ireaded portion F and the bottle to approach the nozzle H.During this turning movement a projection or arm L on the upright Acomesinto contact with the movable part E of the bottle guard or shieldand turns it into the protecting or closed position (seeFigure 4). Thedistance through which the frame moves upwards compared with theangular. movement thereofis such, that engagementrbetweeni the bottleand the nozzle H cannot take place ,until the movab-lepart E of thebottle. guard. or shield has assumed its nearly ,closed position, theactual. engagement between the bottleand the nozzle H occurring duringthe last part ofthe. angular movement of the vframe during which. therear end. of the projection or arm; L comesagainst the mov- ,able part Eof thebottle guard or shield andretains it in its protecting orclosedlposition while the frame is completing its. up

ward movementto bring the bottle into contact with the nozzle Hwhereupon the aerating gasisadmitted: to the .bottle invthe usualmanner. After the aerating. operation has beenucomspleted the. frame isturnedvin the :opposite direction so as to lower the bottle from thenozzle I-Lihut thebottle guard or v shield isstill :kept in, itsprotecting or :closed vposition by the rear end cof the projection .orarm L, untiltthe frame has been turned sufficiently, to move it theupright A out ofthepath of the movablepart Ei" ofthe bottle guardzorshield, whereupon the latter .is able to assumeits' open position undertheinfiuence of the aforesaid springs. M. and

the bottle thencanbe removed from the apparatus. The rear end of" theprojection or 7 arm Luis provided. with a roller [to reduce frictionwhen contacting with the movable part E1 of the bottle guardlor'shield.

Instead ofim-parting upward and downward movement to the. frame toeffect the engagement and disengagement of the. bottle with the nozzleH, the bottle-platform D may be moved upward and: downward. in theframe; An example of this is given in Figportion vor neck 6Z havingacam-shaped sur-' I ures 5- to 8 wherein the bottle platform- D islooselymounted in the lowerpart of the frame and has a downwardlyprojecting face cl wliich cooperates with acorresponding cam-shapedsurface cl? on a fixed mem her (1 carried by the horizontal part A oftheframe. The neck 03 is providedwith a handle J by which it can:beYrotated,-thereby raising or lowering the bottle platform D on thefixed member d to bring the bottle into or out of engagement with the:nozzle H. The bottle platform has a spindle cl which passes through thefixed member is surrounded by a spring d hsituated between the lowersurface of the horizontal part A ofthe frame and a nut on the end ofsaid spindle, the object of the spindle beingto guide the bottleplatform-during its movements and of the spring to assist-the bottleplatform to return to its lowest position. In this casethe bottle guard:or shield is moved into its protecting or closed position'by apin Lattached to the hand-1e J and exten'd'ingvertically upwards therefrom,said pin coming into contact withv the movable part E" of the bottleguard of the sl'iield when the handled is operated as shewn in the twopositions of the parts in Figure 8. Instead of moving the bottleplatform upwards and downwardsby a cam device a screw-thread devicemight be used to give the necessary movements;

In Figures 5 to 8 the frame of the apparatus is shewn with an extension:piece i shaped at its outer endto fit roundthe- Wall of the aerating gascontainer or cylinder, the object of which is to hold the apparatussteady during use.
